Artificial Photosynthesis to Generate Hydrogen Gets $1.4 Million Funding From DOE

A University of Rochester team has been awarded $1.7 million to generate hydrogen fuel with sunlight using artificial photosynthesis and nanotubes. Generating hydrogen without using a fossil fuel is not easy. Using sunlight to split hydrogen off from water has been done before, but the process has not been cheap or efficient.

They propose to change that by dividing the nanoscale process into three separate modules that can be manipulated separately to isolate the process of gathering sunlight from the process of generating hydrogen.

This way they can better control each step.

Laser Treatment Could Make Plain Light Bulb Much More Efficient

Could a regular light bulb end up being an energy efficient competitor to a compact fluorescent bulb? Researchers at the University of Rochester say yes.

A team of optics researchers at the school say they’ve developed a process that makes a 100-watt incandescent bulb use less electricity than a 60-watt bulb. The process, they say, would keep the cost of a traditional light bulb well under that of its fluorescent counterpart while maintaining the more pleasant light an incandescent bulb gives off.

Professor Chunlei Guo (pictured above) and his team developed a laser process that treats the tungsten filament in a traditional bulb. The process creates nano- and micro- level structures on the filament that dramatically improve its efficiency.

Leftover Grease Powers University Bus and Research

At most college dining halls, they’ll fry just about anything.

Wings, mozzarella sticks, fries and onion rings. Old shoe leather (wait, maybe that’s just a memory of how things tasted at my college dining hall.) All that frying leaves a lot of leftover grease and oil.

At the University of Rochester, a group of students used that oil as the foundation for a business plan that has produced both a biodiesel powered shuttle bus and a new building for biofuel experimentation. The project will hit a milestone on Earth Day, when university President Joel Seligman will help send the shuttle bus off on its first trips around campus, including a tour of the new building.
